Hobby 750S, about 27 ft, plus trailer, whats that, about 10/12 ft, ish./ Never measured it, but all quite manageable. Reversing cam lets you see whats happening, but I have always driven long units so isn't a problem and reversing is a lot easier than you would think. Power is the 2.8JTD Fiat remapped, pulls it all a treat. Also, the motorcycle rack sits on the rear as well, in front of the trailer, so can get my Guzzie on there in case the weather is nice. Have to cover all eventualities. And yes, to all those that remind me, thank you, the power cable is coiled up, hanging across the dis. box so no trip hazard, and no, it doesn't produce heat because there are about 10 coils, 1 metre across, they are not on a drum, so "air cooled", and the amperage being pulled makes not a jot of difference. I sometimes drop the coils into a large placky bag to keep them tidy. There may be a little induction from the coils but as I don't have anything lower than 240 within 6 inches of it that doesn't affect it either. I have used this method since the Caravan days, [are we allolwed to use that word] and even in Spain etc, not a heat problem. You only need to uncoil from the drum, mainly because there are a lot more coils on a drum, being smaller diameter, the air cant get at the lower coils, and if you do pull a high amperage it "may" get warm. By the time it does get warm, I would be pulling more amperage than the site could supply..lol..Anyway, thats what trips and fuses are for...lol..In 35 years electrics work, including site work, never come across the problem. I have seen more injuries from people tripping over cables, especially at night, and where alcohol is concerned..A tidy cable is more important and less dangerous. Used this method for years. Saw one guy who tripped over a cable at night and promptly put a awing peg into his forehead when he fell over. Nasty.
